Hi guys, I'm new here and need some professional advice.

I'm upgrading from a numark total kontrol, and am wondering what to buy next. I've heard great stuff about the S4, but also thinking about the allen & heath Xone.. or the VCI-100? I have $1000 to spend on some equipment, and am primarily looking for a controller and maybe midi keyboard or something.

Oh, and I'm on a Mac, using Reason, Ableton and Traktor.

Any advice is much appreciated!

tldr: I have $1000 to spend on gear, what should I get?
